C220CDiSport

I’m in the UK and new to this forum so apologies if my request has been posted before. I have had my 2012 C220CDi Sport (W204) with Brabus chip from new and wish to fit a dash cam. I’ve been looking at cameras on Kammu.com and luview.com as they have a neat design being integrated in the plastic cover in front of the rear view mirror. Does anyone have cameras from either of these as would appreciate any feedback as can’t find any reviews.
